Pneumatic butterfly valve model name coding method

Pneumatic butterfly valve model preparation method, code naming method, only in China
Pneumatic butterfly valve is one of the most common valves in industrial piping systems. It has the functions of switch cut-off, proportional adjustment, and emergency cut-off. It also has rapid switching, simple structure and

easy maintenance. It is used more and more on low-pressure large and medium-diameter pipelines. ! However, due to the various connection methods and structural forms of pneumatic butterfly valves, many people are often uncertain when choosing butterfly valve models. In order to reduce this situation, our company provides pneumatic butterfly valve model compilation instructions for everyone. Reference and understanding!
Pneumatic butterfly valve model preparation instructions include the addition of additional conditions for the butterfly valve, the difference in connection methods, the upgrade of the transmission mode, the change of the structure, the level of valve pressure, and the requirements for temperature, pressure, corrosion and material. Hope It is helpful to everyone in the selection! To
